Lo esencial

A new layer of surface hoar is growing up to 8mm that will likely be a problem when the next storm arrives.  Continue to watch for this weak areas where you may trigger the basal weaknesses.

Problemas de aludes

  • Wind Slabs

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Possible
    Tamaño
    1–3
    Thin lenses of hard slabs can be found in alpine  terrain.  This will be  most susceptible to human triggerring from thin weak areas.

  • Persistent Slabs

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Possible
    Tamaño
    1–3
    Be cautious around the treeline elevation where this layer seems most triggerable.

  • Deep Persistent Slabs

    This interface is still in forecasters minds at the base of the snowpack.  In many areas, this crust is beginning to facet out.

Confidence

Good

Weather Forecast

Warm temperatures continue and winds are forecast to increase as we move into the weekend.  We aren't expecting any new snow over the next 24hrs but there will be a pulse on Friday that may give us 5 cm or so. 

Avalanche Summary

No new avalanche observations.

Snowpack Summary

Very little change out there at this time.  Open alpine terrain is wind affects even areas down into treeline are showing evidence of wind affected snow surface.  The dec 13th crust is being found up to 2200m down 30-50cm and is continuing to produce moderate sheers on a layer of FC both above and below this layer.  Deeper in the snowpack the Nov 6th crust persist but is showing signs of breaking down.  A new layer of surface hoar is widespread in all areas below treeline and sheltered areas in the Alpine that will likely be a problem when the next storm, or a storm, arrives.
